        Configures the total number of mutexes to allocate. Berkeley DB
        allocates a default number of mutexes based on the initial
        configuration of the database environment. That default calculation
        may be too small if the application has an unusual need for
        mutexes. This parameter is used to specify an absolute number of
        mutexes to allocate.
    </p>
      <p>
         The syntax of this parameter in the <a href="../../programmer_reference/env_db_config.html#env_db_config.DB_CONFIG" class="olink">DB_CONFIG</a> file is a single
         line with the string <code class="literal">mutex_set_max</code>, one or more
         whitespace characters, and the total number of mutexes. Because
         the DB_CONFIG file is read when the database environment is
         opened, it will silently overrule configuration done before that
         time.
